> Interesting question! When mankind will really need to calculate costs and try to get rid of such an entrenched "habits" as av-scanning (same as to crypto-mining nowadays), it could be too late to do something. > Or take banks. I was amazed to see how much manual work is done in financial institutions. Skyscrapers with bank name on top of it filled with tens of thousands people. Everyone has computer, among other things burning electricity. Separately, datacenters. How does it compares to crypto? I doubt it's less, if sum up all banks. You'd be likely wrong. Bitcoin now uses the same energy as the whole country of Argentina with 43 million people. For comparison Bank of America has 200 000 employees. Are there more than 200 banks of that size, maybe but I'm doubtful. Moreover Argentinas energy consumption includes vastly more energy intensive endeavours than banking (manufacturing, mining etc). from that estimate I would be very doubtful that the whole banking sector uses more energy than bitcoin mining. Moreover as others pointed out the banking sector serves many more people with many services that bitcoin can't provide.
